Subsig

Updated July 24, 2026

Overview / Description

Subsig is an AI visibility and reputation management tool that runs autonomous agents to monitor and improve how B2B companies appear in AI-driven search and recommendation systems. As buyers increasingly ask ChatGPT, Perplexity, and similar platforms which products to use, Subsig tracks where a brand shows up (or doesn't) and produces structured action plans to improve that presence.

The platform consolidates signals from review sites, social mentions, and AI prompt responses into nine agent-powered workflows: Root Cause Analysis for diagnosing metric drops with confidence rankings, Prompts Discovery to surface the exact buyer questions being asked to AI systems, Competitive Benchmark for comparing AI visibility against named competitors, and an AI Visibility Roadmap that produces step-by-step improvement plans. Additional agents cover a Social Mentions Plan, Reputation Playbook, Review and Listings gap analysis, Keyword Strategy, and Authority Building that drafts community contributions for human approval before posting.

Access is available through Claude, Slack, and MCP integrations, supporting over 100 languages. Subsig is built specifically for product-led AI and B2B SaaS companies and counts over 70 customers including BuildingRadar, Photoroom, Kittl, WebinarGeek, and Hostinger. The platform offers a free entry point and positions itself as four services in one subscription with pay-per-need billing rather than bundled credits.
